Horrid means extremely unpleasant. A horrid smell, a horrid thing to say, horrid weather.
It is milder than horrible in modern use and slightly old-fashioned, which is why it is used so much by and about children — Horrid Henry being the obvious case. It once meant bristling with horror, and Milton used it that way. Note horrific, which is far stronger and belongs to disasters; horrendous; and that horrid, horrible and horrific are three degrees of the same Latin word and are used at quite different weights.
